This is the scenario I'm talking about. Green filled, black edged are transactions of the honest network. Red edged - are transactions of the attacker. The doublespends are filled with yellow.
As far as I understand your algo, weight of the red tip is greater by 3 than weight of the green tip.



Does this assume that the merchant waited for enough confirmations? Because his transaction seems to have very little confirmation.
My picture contains as low amount of transaction as possible, just to express the idea. You can imagine several more transactions of the honest network on top of the green tip, but many more red transactions above the second doublespend.
Our point is that normally the left yellow tx would be referenced e.g. already by the second green tx.
